Abstract
The utility model discloses an injection mold with a gear type thread core-pulling mechanism. The injection mold comprises a fixed mold plate, a movable mold plate and a movable mold clapboard, wherein a rotating core and a connecting rod are arranged and connected on the movable mold clapboard in a rotating way; a first straight gear sleeve and a second straight gear sleeve are respectively connected on the rotating core and the connecting rod by keys; the first straight gear sleeve and the second straight gear sleeve are connected by paired gear pairs; a bevel gear shaft is also arranged on the movable mold plate; the bevel gear shaft is connected with the second straight gear sleeve by a bevel gear pair; a straight gear rack is fixedly arranged on the fixed mold plate; and the straight gear rack is connected with the bevel gear shaft by a straight gear pair. The injection mold disclosed by the utility model adopts a way that the straight gear pair and the bevel gear pair are combined, the movement of the movable mold plate and the fixed mold plate are converted into the rotating movement of the molding internal thread type core, and a plastic part with an internal thread can automatically demold ingeniously; and the injection mold adopting the scheme is simple in structure and convenient to produce and machine.
Description
Technical field
The utility model relates to the injection mold technical field, especially a kind of injection mold with gear type screw thread core pulling mechanism.
Background technology
In known injection mold technical field, general plastic fastening all has the structure of internal thread, common core-pulling mechanism can't be finished automatically smoothly and loose core, so small plastic parts is by generally passing through forced stripper mechanism, large-scale plastic parts is generally by manually taking out, so not only cause easily the damage of plastic, production efficiency is low simultaneously.
The utility model content
The technical problems to be solved in the utility model is: a kind of injection mold with gear type screw thread core pulling mechanism is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of injection mold with gear type screw thread core pulling mechanism, comprise solid plate, moving platen and dynamic model dividing plate, be rotationally connected to be equipped with at described dynamic model dividing plate and rotate core and connecting rod, key is connected with the first straight-tooth wheel case and the second straight-tooth wheel case respectively on described rotation core and connecting rod, described the first straight-tooth wheel case be connected the gear pair of straight-tooth wheel case by pairing and connect, bevel gear shaft also is installed on the described moving platen, and described bevel gear shaft is connected with the second straight-tooth wheel case by bevel gear pair, be installed with the spur gear bar at described solid plate, described spur gear bar is connected with bevel gear shaft by spur gear pair.
The beneficial effects of the utility model are: the mode of the utility model by adopting spur gear pair to combine with bevel gear pair, dividing the conversion of motion of mould with moving platen and solid plate is the rotational motion of moulding internal thread core, cleverly so that have the plastic automatic demoulding of internal thread, this programme is simple in structure, makes easy to process.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is cross-sectional view of the present utility model.
Among the figure: 1. solid plate, 2. moving platen, 3. the dynamic model dividing plate 4. rotates core, 4-1. the first straight-tooth wheel case, 5. connecting rod, 5-1. the second straight-tooth wheel case, 6. bevel gear shaft, 7. spur gear bar.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of injection mold with gear type screw thread core pulling mechanism of the utility model as shown in Figure 1, comprise solid plate 1, moving platen 2 and dynamic model dividing plate 3, be rotationally connected to be equipped with at described dynamic model dividing plate 3 and rotate core 4 and connecting rod 5, key is connected with the first straight-tooth wheel case 4-1 and the second straight-tooth wheel case 5-1 respectively on described rotation core 4 and connecting rod 5, described the first straight-tooth wheel case 4-1 be connected the gear pair of straight-tooth wheel case 5-1 by pairing and connect, on the described moving platen 2 bevel gear shaft 6 is installed also, and described bevel gear shaft 6 is connected with the second straight-tooth wheel case 5-1 by bevel gear pair, be installed with spur gear bar 7 at described solid plate 1, described spur gear bar 7 is connected with bevel gear shaft 6 by spur gear pair.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
